Now I’m sure (I’ve checked against someone else’s Plasma behaviour): I’m missing the option to resize panels (make them not use the full width of the screen). Here’s what I have in “more options” (bottom screen):
I’m trying to reproduce what the theme (Zafiro v3) did with the bottom panel of the top screen.
The forum won’t let me add another screenshot, but I also don’t have the middle resizing bar when in edit mode (the one with the handles allowing to modify the width of the panel). Plasma seems to be forcing me to use the “maximize” option (since there is no checkbox next to it, I can’t uncheck it…)
the ruler with the handles to resize the width of the panel
the “More options” items “Default”, “Size/width/height/thicknes” or whatever it’s supposed to be named
the possibility to check/uncheck the “maximize panel” option
any mention of these size parameters in ~/.config/plasma-org.kde.plasma.desktop-appletsrc.
It would help a lot if someone knew how to achieve any size for the panel through editing the config file, in the event where no one can guess why I’m missing these options in the GUI… Any help would be great!
By the way, I have the same problem on 2 different Manjaro/Plasma 5 laptops, which makes me think this issue should be easily reproced… Or at least it shows that it is probably not just a bug but rather a config issue.
